产品描述
This assay employs the competitive enzyme immunoassay technique. Determine the level of NA/NE(Noradrenaline/Norepinephrine) in the sample. Add standard or sample to the microplate that have been pre-coated with NA/NE(Noradrenaline/Norepinephrine) antigen. Add Biotin-conjugated anti-NA/NE(Noradrenaline/Norepinephrine) antibody. It is then combined with HRP-conjugated streptavidin to form an immune complex, then incubated and washed to remove unbound enzyme, and then added to the chromogenic substrate TMB to produce a blue color, and converted to the final yellow under the action of acid. Finally, the absorbance (OD) value was measured at 450 nm. The concentration of NA/NE(Noradrenaline/Norepinephrine) in the sample is inversely proportional to the OD value. The concentration of NA/NE(Noradrenaline/Norepinephrine) in the sample can be calculated by drawing a standard curve.
